CAR COUPLING AND BRAKE.

Specification of Letters Yatent.

Patented Mar. 10, 1914.

Application filed August 31, 1912. Serial No. 718,073.

To all whom it may concern Be it known that I, PHILANDER K. TUCKER, a citizen of the United States, residing at Sioux Falls. in the county of Minnehalia and State of South Dakota, have invented new and useful Improvements in Car Couplings and Brakes, of which the following is a specification.

This invention relates to combined alr hose and car couplers, the object of the device being to provide in one device a conpler for the cars and acoupler for the air hose and to automatically open connection between the car pipes simultaneously with the coupling of the cars, the connection being made directly through the tongues of the car coupling knuckles.

Further objects of the invention is to pro vide means for holding the tongues of the coupler in tight engagement with each other at all times so as to prevent any escape of air which might be caused by sudden relaxation of the tension on the couplers.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing which forms a part of this invention, and in which,

Figure 1 is a side elevation. Fig. 2 is a horizontal section on the line 22 of Fig. 1. Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 1. Fig. 4 is a face view of one of the tongue gaskets mounted in the tongue of the coupler. Fig. 5 is a detail perspective sectional view showing the manner of mounting the tongue springs.

Referring more particularly to the drawings 1 and 2 represent the separate coupler heads which are adapted to be connected and which are recessed as shown at 3 so as to provide for the improvement of the tail 4 over each coupler knuckle 5. These coupler knuckles are pivoted as shown to the heads at 6 and are provided as usual with the tail 4 and tongue 7. In each tail there is formed a relatively large chamber 8 which adapted to receive a valve nipple 9 removably arranged into :1 lug or casting 10 secured to the head of the bolts 11, each head is provided with similar parts and a description of one will therefore suffice for both. The nipple 9 has a foraminous or apertured lower end 12 and slidably mounted in the nipple is a valve stem 13 carrying a valve disk 14.- at its upper end adapted to set against a gasket 15 embedded in the upper end of the boss or casting 10 and surrounding the central opening 16 therein which communicates with the nipple. The valve disk is normally held against the gasket 15 by a spring 17 which is arranged between the disk 14 and a shoulder 18 formed in a connected elbow 19 to which the hose 20 is secured. The lower end of the valve stem 13 projects through the nipple and is adapted to be engaged by the head of an adjusting stud 21 projecting into the chamber 8 so as to strike the valve stem when the cars are coupled. The tail also carries a packing washer 22 which surrounds the nipple 9 when the knuckle is in closed position so as to prevent the escape of air through the chamber 8 to the outside.

Communicating with the chamber 8 and extending through the knuckle from the tail to an intermediate portion of the tongue is a channel23 which communicates with a plurality of bolts 24 formed in alinement vertically across the tongue 7. These bolts have trained thercinto suitable nipples 24, 25 which hold in position through a retainer 26 the packing plate 27 which, as shown in Fig. 2, projects beyond the face of the tongue and is adapted for engagement with the gasket of the opposite tongue as will be readily understood.

Carried by the tail of each knuckle is a leaf spring 28 having its free end operating within the recess 29 and its intermediate portion bowed to engage the tongue of the opposite knuckle so that both tongues will be held in firm engagement with each other irrespective of the movement between the heads 1 and 2. These springs are preferably seated in a recess 30 formed in the tongue and secured by bolts 31 which extend through the overhanging lip 32 formed by the recess through the spring and into the tail of the coupler, the aperture shown at 33 is provided for the locking pin or wedge bolts which hold the tongue in interlocking position when the cars are coupled.

Having thus described the invention, what is claimed, is

1. A car and air hose coupler of the J annoy type comprising coupling heads, knuckles intermediately pivoted in said heads and provided with fluid passages therein having their rear ends expanded, an air hose extending in the side of said heads and projecting into the expanded end of the passages of saidknuckles, valves in said air hose normally held closed, and valve stems extending from said valves into the expanded .end of the passages of said knuckles to engage the walls of said passages when said knuckles are in engagement with each other thereby opening said valves.

2. A car and hose coupler of the J anney type comprising coupling heads, substantially goose neck knuckles intermediately pivoted in said heads, a flat spring having an end thereof secured to the inner side of the tail of each of said knuckles and being bowed intermediate its ends, the bowed portion of said spring being adapted to en gage the tongue of the mating knuckles to constantly press the same against each other when the same are coupled, said knuckles being provided with air passages therein adapte to communicate at the tongues thereof.

3. In a combined car and air hose coupler, a combination with a drawing head, of a knuckle intermediately pivoted in said head and having a fluid passage therein extend ing from end to end, said passagebeing hose removably connected with said head and adapted to register in said passage, a nipple carried by said hose and extending into the enlarged portion of said passage, a valve seated upon one end of said nipple controlling the passage of air into the head, a spring in said hose normally closing said valve, the valve stein carried by said valve and projecting through the opposite end of the nipple, an adjustable stud in said pasenlarged in the tail of said knuckle, an airsage for engaging said valve stem to raise the same to allow air to escape into said passage when the knuckle is engaged by a complemental coupling head.

In testimony whereof I aflix my signature in presence of two witnesses.

PHILANDER KILE TUCKER.
